Silver Steel Cut Lengths

Engineers Studs / Threaded studs

Engineers Studs are forged steel with a rolled thread. These studs are suitable for many applications due to their tough nature and wide range of sizes. In engineering studs are mostly used in assembly with T-nuts, fixture nuts, clamps or screwed directly into the fixture.

What are Engineers Studs?

Stud bolts known as studs are categorized into 3 basic types: Tap End Stud Bolts, Fully Threaded Stud Bolts, and Double End Stud Bolts. Each of these have different engineering applications. Tap end studs have threads at extreme ends of the stud having unequal thread length, but double end stud bolts are differ in that they have equal thread length at both ends. Fully threaded studs are threaded fully across the body for full engagement of the matings nuts or similar parts. Apart from these there are stud bolts for flanges which are fully threaded studs with chamfered ends, and double end studs with reduced shank for special bolting applications. If it's studs that are not completely threaded your looking for, there are two types of studs to look at: full-bodied studs, and undercut studs. Let's look at Full-bodied studs, they have a shank equal to the major diameter of the thread. Now undercut studs are slightly different and have a shank equal to the pitch diameter of the screw thread. These undercut studs are designed to better distribute axial stresses. Full-bodied studs have stresses that are greater in the threads than in the shank.

Stronger Studs - Undercut / Rolled Thread

Undercut studs (rolled thread) are also stronger because the metal is "rolled" up to the major diameter, not removed. This preserves the grain of the steel, and in some cases even enhances it. Full bodied studs (cut thread) are weaker because metal is removed to create the thread, disturbing the grain of the steel.
